RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent N o. 419,619, dated January 21, 1890. Application led August 24:, 1889. Serial No. 321,826. (No model.)

T0 all whom, t may concern:

Be it known that I, SAMUEL LovE ADKINs, a citizen of the United States, residing at Hinds Creek, in the county of Anderson and State of Tennessee, have invented a new and useful Railway-Gate, of which the following is a specification.

This invention has relation to railway-gates for stock-gaps, by which is meant a gate arranged in a narrow gap for the purpose ot preventing stock from passing' therethrough, whereby the lives of the same are endangered by passing trains.

Among the objects in view are to provide a simple pair of gates, one arranged at each side of the track, and mechanism connecting the track with the gates, whereby the passing train will serve to open the gate for the passage of the train, said gates being automatically closed after the train has passed,the gates be operated from either direction, if desired.

With these general objects in view the invention consists in mounting a .loose section of rails upon a suitable trestle and pivoting the ends of the section to the opposite ends of the main rails, and in supporting said loose section upon swinging arms or Vlevers connected by a connecting-rod and connecting said rod with a pivoted lever at each side of the trestle, which is usually connected with the swinging gate-post; and, furthermore, in the provision of a returning-spring, whereby said gates are automatically closed after the weight of the train has passed from over the f loose section.

Referring to the drawings, Figure 1 is a plan of a gate embodying my invention. Fig. 2 is a longitudinal section on the line :t of Fig. l. Fig. 3 is a transverse section; Fig. 4, a detail in perspective of one of the swinging gates.

Like numerals of reference indicate like parts in all the figures of the drawings.

In constructing the trestle which forms a portion of the road-bed,I provide that portion of the bed within the gap with longitudinally-opposite pairs of beams 1, each pair of which is provided at equidistant points at each side of the gate with bearings 2, the bearings of one pair at one side of the gate aligning with those of the opposite pair. Suitable ties 3 are arranged at intervals across the opposite pairs of beams or sleepers, and in each pair of bearings 2, upon bearing-pins 4, are loosely-pivoted levers 5', the lower ends of which depend between their respectivo pairs of beams 1 and the upper ends of which are slightly curved, as at 6, and bifurcated, as at 7, and provided with loose pulleys 8.

9 represents the two rails, the adjacent ends of which incline upwardly, and 10 the intermediate loose sections engaging the rails 9, the loose sections being supported upon the longitudinally-opposite pairs of levers 5 and upon the friction-pulleys thereof. The ends of the intermediate loose sections 10 are shouldered, as at 11, and overlap similar opposite shoulders 12, formed in the ends of the -main rails 9, and through said shoulders is inserted a pin 13, whereby the intermediate loose rail-sections are pivotally connected to the main rail-section.

14 represents opposite connecting-rods, the ends of which are dovetailed to embrace the base of the main rails 9 and prevent the same from spreading at those points nextthe pivoted point of connection with the loose sections.

15 represents opposite levers, theinner ends of which are pivoted, as at 16, to a central tie,

an'd the outer ends of which are dovetailed, as at 17, to embrace the webs of the rail-sections 10, said levers 15 being oppositely disposed and each embracing one section, and by reason of their pivotal connection at their rear ends said loose-sections may be depressed and yet no spreading thereof occur.

The lower ends of the arms or levers 5 are bifurcated, as at 1S, and by means of a pin 19, inserted through perforations in the bif furcations, a connecting-rod 20 loosely connects each pair of longitudinally .opposite levers. The connecting-rods 20 pass beyond their point of connection with the arms 5, and their ends pass through bearing-openings 21, formed in blocks 22, located between the pairs of beams 1, and between their points of connection with the arms 5 and said blocks said rods are provided with coiled springs 23, adapted to maintain the swinging arms or levers 5 in a substantially vertical position.

At each side of the outer` beams 1 are mounted upwardly-projecting bearing-trunnions 24,

IOO

and pivoted upon the same are oscillatinglcvers 25, the longer portions of the levers being their outer ends, which are provided with upwardly-projectng studs i6. The inner ends of the levers 25 are bifurcated, as at 27, and embrace the central portion ot" the connecting-rods 20, and are pivoted thereto by a vertical pin 28.

29 represents opposite standards, arranged at each side of a trestle and at the mouth oi: a gap, said standards, if desired, being connected by a transverse tie-bar 30, provided near the standards 2) with bearings 3l in a vertical line, with similar bearings 32 formed in a transverse base or beam 33, extending under the trestle, or in any suitable hearingblock. In the vertically-aligned bearings 3l and 32 are mounted pivotal gate-posts 3l, from which project lateral gate-bars 35 and 36, the two upper bars overlapping the road, and those of one gate meeting those oi the opposite gate, thus completely elosingthe gap. The lower bar 3G is shorter than the upper bar 35 and nearly reaches the beams l, said lateral bars being connected by a tie-bar 37. Frein the lower ends of the gate-posts 3l there project inwardly-slotted levers 3S, which receive the upwardly-projeeting studs 2G,loeated at the outer ends of the levers 35.

The operation of my invention is as follows: An approaching train weighs upon the intermediate sections of rails l0, which are supported by the rocking arms 5, and by reason of the upper portions of said arms being curved or offset from the vertical pivot line thereof the sections 10 are depressed and the levers or rocking arms thrown out of a vertical line against the tension ot the return -springs 23. The depression of either pair of arms will by reason of the connectingrods 20 likewise operate the opposite rocking arms, and as the connecting-rods are swung in either direction they carry with them the inner shorter end of the levers 25, the outer ends of which are oseillated or swung a short distance and likewise swing, through the medium of the slotted lever connected with the same, the gate-posts 3l and their gates. lVhen the weight of the train is removed from the sections l0, the springs 2l, operating against the lower ends of the rock-arms 5, serve to return said rock-arms to a vertical position, and through the connecting-rods and other mechanism just described the gates are returned to a closed position.

Having described my invention, what I claim isl. A road-bed provided with ties,in combination with movable rail-sections arranged above the ties, pivoted rocking levers for supporting the rails, and opposite rail-embracing levers, the inner ends of which are pivoted to the ties, whereby the rails may be depressed for operating a gate mechanism and yet prevented from lateral spread, substantially as described.
